What dichotomy highlights the functional shift in wristwatch use between early space travel and modern ISS operations?
Answer
In the early days, a reliable watch *was* the technology; today it is specialized (EVA) or personal (ISS).
The text notes a functional shift where early on, a watch was essential core technology, whereas today, integrated spacecraft systems handle timing, allowing wristwatches to serve either a critical backup role for EVAs or a personal role inside the station.
